Ok so I realize it’s most likely muscle strain but my anxious mind won’t allow that. Went right to heart attack. Been doing with it for roughly an hour now. If I don’t move it doesn’t hurt at all. If I turn my head to the left it pulls and hurts like a ****. If I turn to the right it’s very minimal pain. I’m soaking in a bath right now with my phone in my hand googling symptoms. Ugh. Before I got in the bath i jogged on the treadmill for 5-10 mins just to see what would happen and I was fine. Alittle panic jittery but no catastrophic event took place. Like I said. I know there’s a 99% chance it’s just a tight muscle but when it’s pulling in the left side of my upper back and chest I can only think one thing.
